FGL590M Dia. 25 mm SM1-Mounted Colored Glass Filter; 590nm Longpass

The FGL590M is a color glass filter developed by Thorlabs, a leading vendor in the optical industry. This filter, with a catalog number FGL590M, is specifically designed for use in optical systems that require longpass filtration at 590nm. The filter is mounted in an SM1-compatible design, ensuring ease of integration into various optical systems.

The FGL590M filter boasts a circular geometry with a diameter of 25 mm and a thickness of 2 mm, making it a compact yet efficient optical component. The filter's material is n-bk7 Schott, a high-quality glass known for its excellent optical properties.

The filter's primary function is to allow light with wavelengths longer than 590nm to pass through while blocking shorter wavelengths. This is achieved through the application of a specialized coating, denoted as 'tho fgl590' on both the front and back surfaces of the filter.

The FGL590M filter is currently in stock and available for immediate purchase through the Thorlabs website. For more detailed information, including technical specifications and purchasing options, please refer to the provided weblink.
